Description

Technical Field

[0001] This application relates to the field of flexible screens, and more particularly to a die-bonding carrier for flexible screens. Background Technology

[0002] Traditional die-bonding carriers for flexible displays typically use mechanical pressing or vacuum adsorption to fix the flexible display substrate. Their core objective is to bond the flexible display to the carrier surface using physical pressure or negative pressure. However, due to their thinness and flexibility, flexible displays are prone to localized warping or displacement during the pressing process due to uneven stress or positioning deviations, leading to decreased die-bonding accuracy. Especially in high-precision die-bonding processes, traditional carriers struggle to ensure the stability of the flexible display's edge areas, easily causing issues such as bonding misalignment and residual air bubbles, directly impacting the yield and reliability of the display module.

[0003] To improve pressing accuracy, several improvements have been proposed in existing technologies. For example, one approach involves setting a single-sided positioning post on the carrier body and creating a guide groove on the pressure plate that matches the positioning post. Initial positioning is achieved through the interaction of the guide groove and the positioning post when the pressure plate presses down. Another approach uses multiple sets of elastic pressure strips distributed along the edge of the carrier. The deformation of these elastic strips provides uniform pressure, while grooves on the carrier surface constrain the lateral movement of the flexible screen. Furthermore, some solutions attempt to add a temporary adhesive layer to the non-functional areas of the flexible screen, using adhesive to assist in positioning before pressing.

[0004] While the aforementioned existing technologies have improved the pressing accuracy to some extent, significant drawbacks remain: for example, the design of single-sided positioning posts or guide grooves can only restrict displacement in a single direction, and the flexible screen may still experience horizontal shifting or rotation during the pressing process due to insufficient symmetry; secondly, although the elastic pressure strip can provide uniform pressure, it lacks a rigid positioning structure perpendicular to the pressing plane, and cannot effectively suppress the slight deformation of the flexible screen in the vertical direction; furthermore, the temporary adhesive layer in the edge area of ​​the flexible screen requires additional processing of positioning holes or adhesive marks, increasing the process complexity and potentially damaging the functional layers of the flexible screen. Especially when the positioning structures of the carrier and the pressure plate do not form a symmetrical vertical through-fit, existing technologies struggle to achieve synchronous constraint of three-dimensional positioning during the pressing process, leading to localized stress concentration or insufficient bonding accuracy in the flexible screen.

[0005] The purpose of this application is to provide a flexible screen die-bonding carrier for stable clamping.

[0006] According to one aspect of this application, a flexible screen die-bonding carrier is provided, comprising:

[0007] A pressure plate having a pressing plane facing one side, the pressure plate including at least two symmetrically distributed first positioning holes extending perpendicular to the pressing plane;

[0009] The flexible screen has a second positioning hole on its edge area that is adapted to the positioning component;

[0010] When the pressure plate presses the flexible screen onto the bearing surface of the carrier body via the pressing plane, the positioning component passes through the second positioning hole and the first positioning hole in sequence, so that the flexible screen is clamped and fixed between the pressure plate and the carrier body.

[0011] In one specific embodiment, the edge of the pressure plate is provided with a magnetic part, which magnetically engages with the carrier body to clamp and fix the flexible screen between the pressure plate and the carrier body.

[0012] In one specific embodiment, viewed along a plane perpendicular to the pressing plane, the pressing plate has a rectangular structure and extends at one end along its length to form a handheld end, which is used to grasp and separate the pressing plate from the carrier body.

[0014] The depth of the clearance groove is not less than the length of the handheld end that extends beyond the corresponding edge of the vehicle body, and the width of the clearance groove is greater than or equal to the width of the handheld end.

[0015] An operating gap is formed between the bottom sidewall of the clearance groove and the outer edge of the handheld end, which is used to accommodate the force applied by the fingers to separate the pressure plate from the carrier body.

[0016] In one specific embodiment, the pressure plate has a die-bonding groove that matches the outer contour of the flexible screen when projected along the perpendicular plane of the pressing. The die-bonding groove penetrates the pressure plate.

[0017] In one specific embodiment, along a projection perpendicular to the bearing surface, a heat dissipation hole group is formed on the bearing surface of the carrier body, and the distribution area of ​​the heat dissipation hole group is directly opposite to the non-circuit area of ​​the flexible screen;

[0018] The heat dissipation hole group includes at least two rows of heat dissipation holes arranged at intervals along the length direction of the vehicle body, and each row includes at least three heat dissipation holes evenly distributed along the width direction.

[0021] In one specific embodiment, the positioning component includes a first positioning post and a second positioning post. In the length direction of the positioning component, the first positioning post and the second positioning post pass through the first positioning hole and the second positioning hole respectively to fix the pressure plate and the flexible screen.

[0024] This application has the following beneficial effects:

[0025] The first positioning holes, symmetrically distributed on the pressure plate and perpendicular to the pressing plane, and the corresponding positioning components extending from the carrier body form a rigid guide structure that penetrates vertically. Combined with the second positioning holes pre-set on the edge of the flexible screen, the three components work together coaxially to achieve precise three-dimensional alignment of the pressure plate, the flexible screen, and the carrier body. During the pressing process, the positioning components pass through the second positioning holes of the flexible screen and the first positioning holes of the pressure plate in sequence, forming multi-point symmetrical constraints in the vertical direction to ensure uniform distribution of pressing force and suppress horizontal offset or rotation. The perpendicular orthogonal relationship between the pressing plane and the positioning components further strengthens the consistency of the pressing direction and avoids local warping of the flexible screen due to angular deviation.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Please refer to Figure 1 - Figure 4 One embodiment of this application provides a flexible screen die-bonding carrier 100, comprising:

[0037] The pressure plate 1 has a pressing plane 2 facing one side, and the pressure plate 1 includes at least two symmetrically distributed first positioning holes 3 extending perpendicular to the pressing plane 2;

[0038] The carrier body 4 has a positioning component 6 on its bearing surface 5 that corresponds to the first positioning hole 3. The extension direction of the positioning component 6 is perpendicular to the pressing plane 2.

[0039] The flexible screen 7 has a second positioning hole 8 on its edge area that is adapted to the positioning component 6;

[0040] When the pressure plate 1 presses the flexible screen 7 onto the bearing surface 5 of the carrier body 4 via the pressing plane 2, the positioning pin 9 passes through the second positioning hole 8 and the first positioning hole 3 in sequence, so that the flexible screen 7 is clamped and fixed between the pressure plate 1 and the carrier body 4.

[0041] Furthermore, the pressure plate 1 forms a clamping space with the bearing surface 5 of the carrier body 4 through its pressing plane 2. The first positioning holes 3 symmetrically distributed on the pressure plate 1 extend perpendicularly to the positioning components 6 on the carrier body 4. The second positioning holes 8 on the edge of the flexible screen 7 are adapted to the positioning components 6. The three form a through-type coaxial positioning chain during pressing. The perpendicular design of the first positioning holes 3 of the pressure plate 1 and the positioning components 6 ensures that the pressing force is transmitted along a single axis, avoiding stress concentration caused by angular deviation. The symmetrically distributed first positioning holes 3 form mechanical balance fulcrums on both sides of the pressing plane 2. Point symmetry constraints eliminate horizontal degrees of freedom. When the flexible screen 7 is clamped, the second positioning hole 8 on its edge precisely engages with the positioning component 6, restricting the lateral displacement and rotation tendency of the flexible screen 7 within the pressing plane 2. This structure, through vertically penetrating rigid guides and multi-point symmetrical layout, ensures that the pressing pressure is evenly distributed in the non-edge area of ​​the flexible screen 7. At the same time, the gap fit between the positioning hole and the positioning post 9 is used to achieve fine-tuning and alignment of the flexible screen 7, ultimately achieving high-precision positioning and stable clamping in three-dimensional space, avoiding edge warping and air bubble problems caused by traditional single-sided positioning or elastic pressure strips.

[0042] In one specific embodiment, the edge of the pressure plate 1 is provided with a magnetic part 10, which is magnetically engaged with the carrier body 4 so that the flexible screen 7 is clamped and fixed between the pressure plate 1 and the carrier body 4.

[0043] Furthermore, the magnetic part 10 at the edge of the pressure plate 1 is pressed and fixed to the carrier body 4 by magnetic attraction. The magnetic part 10 is distributed circumferentially along the pressure plate 1, and its magnetic pole direction corresponds to the magnetic material in the carrier body 4, forming a closed magnetic circuit to enhance the adsorption strength. The direction of the magnetic attraction is consistent with the vertical axis of the positioning component 6, avoiding interference with positioning accuracy due to lateral magnetic force. The synergistic effect of the magnetic part 10 and the positioning component 6 can automatically trigger magnetic locking when the pressure plate 1 is pressed down to the preset position, realizing the rapid loading and release of the pressing force. Compared with the traditional bolt fixing method, this design eliminates the risk of local overpressure through the uniform distribution of magnetic attraction, and there is no mechanical wear during the magnetic separation process. It is especially suitable for high-efficiency die bonding production lines that require frequent disassembly and assembly. At the same time, the non-contact characteristic of the magnetic part 10 can avoid contamination of the pressing plane 2 and ensure the cleanliness of the flexible screen 7 surface.

[0044] In one specific embodiment, viewed along the perpendicular pressing plane 2, the pressing plate 1 has a rectangular structure and extends at one end along its length to form a handheld end 11, which is used to grasp and separate the pressing plate 1 and the carrier body 4.

[0045] Furthermore, one end of the rectangular pressure plate 1 extends to form a handheld end 11, the length of which is parallel to the pressing plane 2. The gradually changing thickness of the handheld end 11 improves grip stability. The handheld end 11 is connected to the main body of the pressure plate 1 through an arc transition to disperse stress and avoid structural deformation caused by uneven force during pressing. The handheld end 11 is located away from the positioning component 6 area to ensure that it will not interfere with the already aligned flexible screen 7 during operation. Its extension length maintains a safe distance from the edge of the carrier body 4 to prevent accidental collision damage to the positioning structure. This design concentrates the operating torque in the long axis direction of the pressure plate 1 through ergonomic layout and uses the lever principle to reduce the external force required to separate the pressure plate 1. At the same time, the asymmetrical extension structure of the handheld end 11 can serve as a visual positioning mark to help operators quickly identify the direction of the pressure plate 1 and reduce assembly errors.

[0046] In one specific embodiment, when viewed along the perpendicular pressing plane 2, a clearance groove 12 is provided on the side wall of the carrier body 4 at the position opposite to the handheld end 11, and the opening direction of the clearance groove 12 is consistent with the extension direction of the handheld end 11.

[0047] The depth of the clearance groove 12 is not less than the length of the handheld end 11 extending beyond the corresponding edge of the vehicle body 4, and the width of the clearance groove 12 is greater than or equal to the width of the handheld end 11.

[0048] An operating gap is formed between the bottom sidewall of the clearance groove 12 and the outer edge of the handheld end 11 to accommodate the force applied by the fingers to separate the pressure plate 1 from the carrier body 4.

[0049] Furthermore, the clearance groove 12 is formed on the side wall of the vehicle body 4 and is coaxial with the extension direction of the handheld end 11. Its depth matches the protrusion of the handheld end 11. The inner wall of the groove adopts a bevel or rounded corner transition to expand the finger operation space. The width of the operation gap allows the finger pad to apply force. The bottom side wall of the clearance groove 12 and the outer edge of the handheld end 11 form a wedge-shaped separation guide surface. When separating, the finger slides along the wedge-shaped surface to generate a vertical component force. Combined with the controllable magnetic attraction strength of the magnetic part 10, the pressure plate 1 is smoothly separated. The opening direction of the groove is parallel to the pressing plane 2 to avoid the structural strength of the vehicle body 4 being weakened by the groove. At the same time, the edge of the groove is reinforced with a reinforcing rib to compensate for the stiffness. This structure solves the tool dependence problem caused by the lack of a dedicated disassembly structure in traditional vehicles through the dual design of spatial clearance and mechanical guidance, and prevents the flexible screen 7 or positioning component 6 from being scratched during manual separation.

[0050] In one specific embodiment, the pressure plate 1 has a die bonding groove 14 that matches the outer contour of the flexible screen 7 when projected along the perpendicular pressing plane 2, and the die bonding groove 14 penetrates the pressure plate 1.

[0051] Furthermore, the outline of the die bonding tank 14 is fitted with the outer outline of the flexible screen 7 with a clearance, and its depth penetrates the thickness of the pressure plate 1 to expose the die bonding area of ​​the flexible screen 7. The tank wall adopts a stepped or inclined design to reduce the edge contact stress during pressing. The open structure of the die bonding tank 14 allows the die bonding equipment to enter the working area vertically, avoiding process interference caused by the pressure plate 1 blocking. At the same time, a guide inclined surface can be added to the inner wall of the tank to assist the pre-positioning of the flexible screen 7. This design ensures that the pressure plate 1 provides uniform pressure without restricting the degree of freedom of the die bonding process by physically isolating the pressing area and the operating area. It is especially suitable for automated production lines that require multi-process integration. In addition, the through design of the die bonding tank 14 can integrate an optical alignment window to improve process visibility.

[0052] In one specific embodiment, along the projection perpendicular to the bearing surface 5, a heat dissipation hole group 15 is provided on the bearing surface 5 of the carrier body 4, and the distribution area of ​​the heat dissipation hole group 15 is directly opposite to the non-circuit area of ​​the flexible screen 7.

[0053] The heat dissipation hole group 15 includes at least two rows of heat dissipation holes 16 arranged at intervals along the length direction of the vehicle body 4, and each row includes at least three heat dissipation holes 16 evenly distributed along the width direction.

[0054] The heat dissipation hole 16 is a through hole, and its axis is perpendicular to the bearing surface 5.

[0055] Furthermore, the heat dissipation hole group 15 is distributed in the non-circuit corresponding area of ​​the bearing surface 5 of the carrier body 4. The row spacing matches the heat source distribution of the flexible screen 7. The single row of heat dissipation holes 16 is evenly arranged along the width direction to form a continuous heat dissipation channel. The through hole axis is perpendicular to the bearing surface 5 to ensure the shortest heat flow path. The inner surface of the hole wall is polished or coated to reduce airflow resistance. The optimized ratio of the diameter and spacing of the heat dissipation holes 16 balances the heat dissipation efficiency and the structural strength of the carrier. The heat generated during the crystal bonding process is quickly discharged through forced air cooling or natural convection to avoid material deformation or abnormal curing of adhesive caused by local temperature rise in the flexible screen 7. At the same time, the heat dissipation hole group 15 can also serve as a supplement to the vacuum adsorption channel to improve the multi-functional adaptability of the carrier.

[0056] In one specific embodiment, viewed along the vertical bearing surface 5, the heat dissipation hole group 15 includes a plurality of heat dissipation holes 16, and the plurality of heat dissipation holes 16 are rectangularly distributed and extend along the length direction of the carrier body 4.

[0057] Furthermore, rectangularly distributed heat dissipation holes 16 extend along the length of the vehicle body 4 to form a grid-like heat dissipation array. Adjacent rows / columns of holes are staggered to break the thermal boundary layer and improve convective heat transfer efficiency. The long side of the rectangle is aligned with the direction of the thermal expansion coefficient of the vehicle body 4 to reduce structural stress caused by temperature difference. The edge of the hole group adopts a gradient density design to match the thermal distribution gradient of the flexible screen 7. This layout achieves uniform surface temperature of the vehicle through biomimetic heat flow path optimization, avoiding the heat dissipation blind spots caused by traditional circular arrays. It is especially suitable for high-power laser die bonding or high-temperature reflow soldering processes.

[0058] In one specific embodiment, the positioning component 6 includes a first positioning post 17 and a second positioning post 18. In the length direction of the positioning component 6, the first positioning post 17 and the second positioning post 18 pass through the first positioning hole 3 and the second positioning hole 8 respectively to fix the pressure plate 1 and the flexible screen 7.

[0059] Furthermore, the first positioning post 17 and the second positioning post 18 are spaced apart along the length of the positioning component 6, and their diameter difference forms a graded positioning. The thicker post is inserted first into the second positioning hole 8 of the flexible screen 7 to complete the coarse adjustment, and the thinner post is then inserted to achieve precise positioning. The perpendicularity tolerance between the axis of the two posts and the pressing plane 2 is less than 0.01°, ensuring no deviation in the pressing direction. Spiral guide grooves or knurled textures can be added to the surface of the posts to enhance the frictional locking with the positioning holes. This design is compatible with the assembly tolerance of the flexible screen 7 through a phased positioning strategy. At the same time, the two posts work together to suppress torque transmission during the pressing process and prevent edge wrinkles of the flexible screen 7 caused by single-point force.

[0060] In one specific embodiment, when viewed along the direction perpendicular to the pressing plane, each of the four corners of the pressing plate 1 is provided with a first positioning hole 3, and the four first positioning holes 3 are symmetrically distributed along the central axis of the length direction of the pressing plane 2.

[0061] Furthermore, the first positioning holes 3 at the four corners of the pressure plate 1 are symmetrically distributed along the central axis of the length direction, forming a rectangular constraint frame. The center distance of the holes matches the span of the positioning component 6 of the carrier body 4. The diagonal error compensation design of the four holes eliminates the cumulative error of processing. The symmetrical hole positions enable the pressing pressure to form a self-balancing force system in the plane of the pressure plate 1, which counteracts the off-center load effect caused by the uneven thickness of the flexible screen 7. At the same time, the four corner positioning can constrain all translational and rotational degrees of freedom of the pressure plate 1 in the pressing plane 2. Compared with the two-point positioning, this design improves the positioning accuracy to the micron level and allows the use of lower intensity pressing pressure to achieve the same clamping effect, reducing the risk of mechanical damage to the flexible screen 7.

[0062] In one specific embodiment, the vehicle body 4 is made of aluminum.

[0063] Furthermore, the main body 4 of the vehicle is made of aluminum alloy through CNC machining or die casting. Its surface is hard anodized to enhance wear resistance. The low density and high thermal conductivity of aluminum meet the dual requirements of lightweight and efficient heat dissipation. The internal honeycomb reinforcing rib structure maintains the flatness of the vehicle while reducing weight. Compared with traditional stainless steel vehicles, the linear expansion coefficient of aluminum is closer to that of the flexible screen 7 substrate, reducing the relative displacement caused by temperature changes. The selection of this material significantly improves the positioning stability of the vehicle under high and low temperature cycling conditions through physical property matching.

[0064] Therefore, the die-bonding carrier for the flexible screen 7 of this application forms a rigid guide structure through which the first positioning holes 3, symmetrically distributed on the pressure plate 1 and perpendicular to the pressing plane 2, and the corresponding positioning components 6 extending on the carrier body 4 are vertically penetrating. Combined with the second positioning holes 8 pre-set on the edge of the flexible screen 7, the three components achieve precise three-dimensional alignment of the pressure plate 1, the flexible screen 7, and the carrier body 4 through coaxial through-fitting. During the pressing process, the positioning components 6 pass through the second positioning holes 8 of the flexible screen 7 and the first positioning holes 3 of the pressure plate 1 in sequence, forming multi-point symmetrical constraints in the vertical direction to ensure uniform distribution of pressing force and suppress horizontal offset or rotation. The perpendicular orthogonal relationship between the pressing plane 2 and the positioning components 6 further strengthens the consistency of the pressing direction and avoids local warping of the flexible screen 7 due to angular deviation.

[0065] The embodiments described above are merely examples of several implementations of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application.
